..The remaining dimensions-Equability and Irritability-were less clear, and it is possible that additional traits will have to be identified before a more robust structure can be established for these dimensions...

Personality and serotonin transporter genotype interact with social context to affect immunity and viral set-point in simian immunodeficiency virus disease

John P CapitanioDepartment of Psychology, University of California, Davis, CA, USAPsychoneuroendocrinology 29:1300-8. 2004

..We propose that comparative studies of personality in nonhuman primates that parallel studies in humans can increase our understanding of mechanisms whereby personality may relate to mental and physical health outcomes...

..These data suggest that a limited number of personality dimensions exist in adult male rhesus macaques, and that these dimensions have predictive power that is both long-term and cross situational...

Social separation, housing relocation, and survival in simian AIDS: a retrospective analysis

..To test the hypothesis that changes in housing, particularly those involving social separations, would have a negative impact on survival in rhesus monkeys experimentally inoculated with the simian immunodeficiency virus (SIV)...

..The results indicate that social factors can have a significant impact on the course of immunodeficiency disease. Socially induced changes in pituitary-adrenal hormones may be one mechanism mediating this relationship...

Do neonatal bilateral ibotenic acid lesions of the hippocampal formation or of the amygdala impair HPA axis responsiveness and regulation in infant rhesus macaques (Macaca mulatta)?

..Finally, females displayed higher cortisol levels than males, independently of their lesion, indicating that the development of sex differences in the regulation of the HPA axis does not involve the amygdala or hippocampus...

..Finally, we suggest that genetic or environmental factors may mitigate the risk for behavioral dysregulation illustrated in the patterns of behavioral activity and emotional reactivity displayed by infants...

..IDA females did not differ from controls. Adrenocortical response was not significantly affected. These findings may be relevant to functional deficits in human infants with IDA that influence later behavior...

..These data provide new insight into potential mechanisms for the development of behavior and temperament and illuminate new directions for investigating maternal effects, nutritional programming, and developmental plasticity...

HIV-related stigma and knowledge in the United States: prevalence and trends, 1991-1999

..These data reveal a surprising degree of behaviorally induced plasticity in the structure of lymphoid innervation and define a novel pathway by which social factors can modulate immune response and viral pathogenesis...

..These findings are consistent with the hypothesis that structural differences in lymphoid tissue innervation might potentially contribute to relationships between social temperament and immunobiology...
